Evaluating Data Product Exposure Metrics for Use in Epidemiologic Studies of Dust Storms

open access: yesGeoHealth, 2023
Dust storms are increasing in frequency and correlate with adverse health outcomes but remain understudied in the United States (U.S.), partially due to the limited spatio‐temporal coverage, resolution, and accuracy of current data sets.

Drought severity and increased dust storm frequency in the Middle East: a case study from the Tigris–Euphrates alluvial plain, central Iraq

open access: yesWeather, 2019
An increase in dust and sand storms has been experienced in Iraq over recent times and seems likely to increase further under future climate change. Iraq is now known as a highly active source region of dust.

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

open access: yesAdvanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

STUDY SOME PROPERTIES OF LOCAL AND STORM DUST PHENOMENA IN BAGHDAD CITY

open access: yesAl-Mustansiriyah Journal of Science, 2017
This investigation has been conducted to study some properties of local storm dust phenomena in Baghdad city. The monthly average of dust (g/m²)  in Baghdad  range from 10.2 g/m²  in Nov. to 43.7 g/m² in April. The local dust has a high Aerobic bacteria

Study of the Effect of Martian Dust Storms on Ionospheric Electron Density Based on Physical-grid Deep Neural Learning Technology

open access: yesThe Astrophysical Journal, 2023
The behavior of the Martian ionosphere during global dust storms has always been a popular topic. Based on many Mars Atmosphere and Volatile Evolution observations, a Martian ionospheric electron density model is constructed herein using a physical-grid ...

Single‐Nucleus Multi‐Omics Reveals Hypoxia‐Driven Angiogenic Programs and Their Epigenetic Control in Sinonasal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
Single‐nucleus multi‐omics profiling of sinonasal squamous cell carcinoma unveils a hypoxia‐driven angiogenic axis. A specific hypoxic tumor subpopulation orchestrates endothelial tip cell differentiation via epigenetically regulated ADM and VEGFA secretion.

Dust Storm Outbreak in Central Asia After ~3.5 kyr BP

open access: yesGeophysical Research Letters, 2019
The evolution and driving factors underlying dust activity in central Asia remain controversial, particularly in its effects on downwind regions. We present a Holocene dust storm activity record retrieved from the Tarim Basin (TB) and perform linear and ...

Variations of Martian surface albedo: Evidence for yearly dust deposition and removal [PDF]

open access: yes
The purpose is to determine the degree, spatial distribution and timing of the deposition and removal of dust storm fallout, and to relate the current patterns of dust deposition and removal to the long-term evolution of the Martian surface.

Activating the Osteoblastic USP26 Pathway Alleviates Multi‐Organ Fibrosis by Decreasing Insulin Resistance

open access: yesAdvanced Science, EarlyView.
The loss of Ubiquitin Specific Peptidase 26 (USP26) in osteoblasts results in decreased bone formation, as well as multi‐organ fibrosis associated with insulin resistance (IR). Mechanistically, the absence of USP26 reduces glycolysis and lactate accumulation, leading to decreased histone H3 lysine 18 lactylation (H3K18LA) in the promoter region of KH ...
